A CORPORATION OF MASSACHUSETTS COMBINED SWITCH AND JUNCTION BOX 'Applicatlon filed March 17, 1930. Serial No. 436,532.

This invention relates to improvements in switch and junction boxes.

The object of the invention is to provide a combined switch and junction box as a special fitting for direct attachment to an electric motor or the like.

The invention, while not limited thereto,

has been worked out for use in connection with gasoline dispensers of the type having a pump driven by an electric motor. The motor is controlled from a remote point but,

contrary to usual practice in other arts, the

switch is not located at such remote point but is itself operated under remote control by mechanical rather than electrical means.

Gommonly,the control is from the nozzle of the dispensing hose and the requirements of local fire commissioners many times forbid locating the switch near the point at which gasoline is discharged. Therefore, the switch is usually located inside the housing of the gasoline dispensing apparatus along with the motor and its pump. Since under these conditions, the switch cannot be located at a convenient control pointand has to be enclosed in an inaccessible location, the wirin and conduit pipin as well be simplifie as much as possib ent invention is directed. I

The invention provides a unit fitting, havriphery of the motor casing and having a passage through which the motor wires extend;

V a second part forming a unction box, which communicates with said passage and also has an opening through which the service wires extend; and a third part forming a receptacle for a switch and also communicating with the junction box.

By the use of this fitting, one is enabled to effect savings in the cost of installation, both as to the conduit work as well as to the wiring work, as will more particularly appear hereinafter.

Other objects will appear as the detailed description proceeds and will be pointed out in the appended claims.

The invention will be disclosed with reference to the accompanying drawings, in which mag e an to that end the presscribed.

Referring to these drawings; the fitting as shown consists of a one piece article, usually a casting. While the invention is in a unit article, having the various parts hereinafter described, it is not necessarily essential in all cases that these parts be integral although I consider that form to be the'best and the one that I now prefer.

The fitting has a saddle piece 5, or bracket, by which it is supported. In this case, the saddle piece is curved at 6 to conform to the periphery of an electric motor m (Fig. 4) to which it is secured by cap screws passing through holes 7 in the saddle piece, one near each end thereof. Intermediate the ends of the part is a passage 8 through which the leads of the motor are passed. Connected to part 5 centrally between its ends and extend ing at right angles thereto is a part 9 which is hollow to afford a junction box 10. This box has a large opening 11 in one side face and this opening may be closed by the usual cover plate p, secured by screws t, threaded into oles 12 in part 9. The 'part 9 also has an opening 13 to allow service wires to enter box and this opening is preferably located near the opposite end of the box from that to which part 5 is connected. As shown, the opening 13 is threaded to receive iron conduit, although it may equally well be adapted for other styles of conduit or to receive the wires without using any conduit; Connected to the junction box is a part 14 affording a receptacle 15 to receive a-switch, such as s (Fig. 4). An opening 16 is provided in part 14 to receive the switch proper while the cover plate 1' rests on top of the part 14 and is secured thereto, as by screws u, threaded into holes 17.

In use, the motor leads are pushed through passage?iutojunctionboxlO and out through the open end 11 thereof. The cap screws are then applied to fasten the saddle piece 5 to the motor m. This results in a firm support for the entire fitting. One of the motor leads is passed into receptacle 15 and connected to the switch. No splicing is necessary for this purpose because by combining the junction box, switch receptacle and saddle piece into one unitary structure, the arrangement is so compact that the motor lead will be found long enough to extend into the switch receptacle with sufficient extra length to enable the connection to the switch to be conveniently effected. One of the service wires, entering box through passage 13, is also passed into switch receptacle and connected to the switch. The other service wire will be spliced to the other motor lead, after which the switch is fastened in place and cover p applied. Many times but one splice is necessary.

In some cases, as with induction motors, there may be four motor leads. By connecting a certain pair of these leads, the motor will be adapted for operation from a circuit of one voltage while by connecting another pair the motor will be adapted for operation from a circuit of another voltage. There may then be two spliced joints to be made and received in junction box 10, but in any event one spliced joint is saved by the use of my fitting because of the compact structure which enables one motor lead of standard length to reach the switch box and the switch therein.

By locating the service wire passage 13 between the switch receptacle and saddle piece, the service wire which extends to the switch is kept out of the way of the motor leads and more room is left to receive the spliced wires below.

The invention thus affords a unit fitting wherein are combined a switch receptacle,

' junction box and an attaching part which also serves as a wire conduit, the conduit man has simply one fitting to handle as against the three which would otherwise be required. The problem of providing a support for the switch receptacle is solved for him by the provision of the saddle piece which is directlv connected to the motor. This saddle piece affords arms extending from opposite sides of the junction box near the base thereof and the junction box affords a supporting column for the switch receptacle. The wire mans work is simplified and can be more quickly and conveniently performed.

The invention has been disclosed herein, in an embodiment at present preferred for illustrative purposes, but the scope of the invention is defined by the appended claims rather than by the foregoing description.

What I claim is:

1. An article of the class described,'com

prising, as one unitary fitting, a saddle piece having a curved face to fit the periphery of an electric motor and provided with means by which it can be secured thereto, a hollow box-like part connected near one end to the saddle piece at a point intermediate the ends of the latter and extending substantially at right angles thereto, said saddle piece having a passage extending therethrough from said curved face to and through one wall of said part, the opposite wall of said part having a relatively large opening therein, said part also havinga service wire opening therein, a cover detachably secured to said part to close the first named opening, and a second box-like part having an open top and having the bottom wall connected to the other end of the second part with a passage connecting the hollow interiors of both said parts.

2. An article of the class described, comprising as one unitary fitting, a hollow boxlike part forming a switch receptacle and having in one face a relatively large opening to allow insertion of the switch and in an opposite face a smaller opening, a second hollow box-like part forming a junction box and connected at one end with the last named face of the first named part with the interior communicating with said smaller opening, said parts disposed so that their long dimensions lie at right angles and the second part forming a supporting column for the first part, said second part having a relatively large opening in one side face and a smaller opening in the opposite side face, and attaching arms connected to the last named face of said second part near the other end thereof and extending in opposite directions one beyond each of the other two side faces of the second part.

3. An article of the class described, comprising as one unitary fitting, a hollow boxlike part forming a switch receptacle and having in one face a relatively large opening to allow insertion of the switch and in an opposite face a smaller opening, a second hollow box-like part forming a junction box and connected at one end with the last named face of the first named part with the interior communicating with said smaller opening, said parts disposed so that their long dimensions lie at right angles and the second part forming a supporting column for the first part, said second part having a relatively large opening in one side face and a smaller opening in the opposite face, and attaching arms connected to the last named face of said second part near the other end thereof and extending in opposite directions one beyond each of the other two side faces of the second part, the smaller opening in the second boxlike part located centrally between said arms.

In testimony whereof I have atfixed my signature.
